Hansen,Anthony Magee Scientific Corporation Dr. Tony Hansen obtained his M.A. in Physics at the University of Oxford, and his Ph.D. in Physics at the University of California, Berkeley. He started his career in the Atmospheric Aerosol Research Group at Lawrence Berkeley National Laboratory headed by Dr. T. Novakov. This group pioneered the study of carbonaceous aerosols from combustion sources at a time when the very existence or significance of primary particulates was strongly debated. This group coined the phrase “Black Carbon” (BC); developed numerous methods for its detection and quantitation by chemical and physical means; studied its influence on heterogeneous atmospheric chemistry in laboratory and field work; and measured its concentrations from urban areas, through regional and rural studies, and ultimately to the Arctic and the South Pole, to document the global dispersion of BC. Tony Hansen was a key contributor to this body of work in this seminal period, co-authoring more than 40 refereed journal articles. In the course of this research he developed the Aethalometer, an instrument that measures BC in real time by measuring incremental optical absorption on a continuously-collecting filter. Over the years this instrument has been enhanced and improved, leading to its accepted use world-wide for the routine monitoring of BC as well as for specialized research applications. Tony has remained closely connected to the interpretation of scientific data involving measurements of BC, together with presentations at conferences and co- authorship of publications with other scientists. He has served as a reviewer for manuscripts submitted to professional journals, and for research proposals submitted to funding agencies. During his career at LBNL he served on numerous internal and external committees and projects, and more recently has provided input to the evaluation of BC measurement methods at various workshops and meetings around the world.
